Abstract

L'invention se rapporte à un procédé pour découper des pièces à usiner, de préférence des barres, au moyen d'une tête porte-couteaux tournant sur elle-même, et à un dispositif pour la mise en oeuvre du procédé Le procédé est caractérisé par le fait que la vitesse de rotation de la tête porte-couteaux s'accroît pendant le découpage jusqu'à une vitesse la plus grande possible (vitesse de coupe : constante) et qu'alors la tete porte-couteaux, tout en conservant la vitesse qu'elle a atteinte, est déplacée transversalement par rapport à la barre. Le dispositif est caractérisé par le fait que la tête porte-couteaux 1 peut être déplacée par rapport à la pièce à usiner 7. Application au tronçonnage, notamment.The invention relates to a method for cutting workpieces, preferably bars, by means of a knife-holder head rotating on itself, and to a device for carrying out the method. The method is characterized by the fact that the rotation speed of the knife holder head increases during cutting up to the highest possible speed (cutting speed: constant) and that then the knife holder head, while maintaining the speed which it has reached is displaced transversely with respect to the bar. The device is characterized by the fact that the knife-holder head 1 can be moved relative to the workpiece 7. Application to cutting, in particular.
